DETAILS OF INCIDENTS FIXED BY THE PATCH
---------------------------------------
This patch fixes the following Symantec incidents:

Patch ID: 6.1.1.100

* 3520113 (Tracking ID: 3451284)

SYMPTOM:
While allocating extent during write operation, if summary and bitmap data for
filesystem allocation unit get mismatched then the assert hits.

DESCRIPTION:
if extent was allocated using SMAP on the deleted inode, and part of the AU
space is moved from deleted inode to the new inode. At this point SMAP state is
set to VX_EAU_ALLOCATED and EMAP is not initialized. When more space is needed
for new inode, it tries to allocate from the same AU using EMAP and can hit
"f:vx_sum_upd_efree1:2a" assert, as EMAP is not initialized.

RESOLUTION:
Code has been modified to expand AU while moving partial AU space from one inode
to other inode.

* 3536233 (Tracking ID: 3457803)

SYMPTOM:
File System gets disabled with the following message in the system log:
WARNING: V-2-37: vx_metaioerr - vx_iasync_wait - /dev/vx/dsk/testdg/test  file system meta data write error in dev/block

DESCRIPTION:
The inode's incore information gets inconsistent as one of its field is getting modified without the locking protection.

RESOLUTION:
Protect the inode's field properly by taking the lock operation.

* 3583963 (Tracking ID: 3583930)

SYMPTOM:
When external quota file is over-written or restored from backup, new settings which were added after the backup still remain.

DESCRIPTION:
The internal quota file is not always updated with correct limits, so the quotaon operation is to copy the quota limits from external to internal quota file. To complete the copy operation, the extent of external file is compared to the extent of internal file at the corresponding offset.     
If the external quota file is overwritten (or restored to its original copy) and the size of internal file is more than that of external, the quotaon operation does not clear the additional (stale) quota records in the internal file. Later, the sync operation (part of quotaon) copies these stale records from internal to external file. Hence, both internal and external files contain stale records.

RESOLUTION:
The code has been modified to remove the stale records in the internal file at the time of quotaon.

* 3617774 (Tracking ID: 3475194)

SYMPTOM:
Veritas File System (VxFS) fscdsconv(1M) command fails with the following error message:
...
UX:vxfs fscdsconv: INFO: V-3-26130: There are no files violating the CDS limits for this target.
UX:vxfs fscdsconv: INFO: V-3-26047:  Byteswapping in progress ...
UX:vxfs fscdsconv: ERROR: V-3-25656:  Overflow detected
UX:vxfs fscdsconv: ERROR: V-3-24418: fscdsconv: error processing primary inode 
list for fset 999
UX:vxfs fscdsconv: ERROR: V-3-24430: fscdsconv: failed to copy metadata
UX:vxfs fscdsconv: ERROR: V-3-24426: fscdsconv: Failed to migrate.

DESCRIPTION:
The fscdsconv(1M) command takes a filename argument which is used as a recovery failure, to be used to restore the original file system in case of failure when the file system conversion is in progress. This file has two parts: control part and data part. The control part is used to store information about all the metadata like inodes and extents etc. In this instance, the length of the control part is being underestimated for some file systems where there are few inodes, but the average number of extents per file is very large (this can be seen in the fsadm E report).

RESOLUTION:
Make recovery file sparse, start the data part after 1TB offset, and then the control part can do allocating writes to the hole from the beginning of the file.

* 3617788 (Tracking ID: 3604071)

SYMPTOM:
With the thin reclaim feature turned on, you can observe high CPU usage on the vxfs thread process. The backtrace of such kind of threads usually look like this:
	 
	 - vx_dalist_getau
	 - vx_recv_bcastgetemapmsg
	 - vx_recvdele
	 - vx_msg_recvreq
	 - vx_msg_process_thread
	 - vx_kthread_init

DESCRIPTION:
In the routine to get the broadcast information of a node which contains maps of Allocation Units (AUs) for which node holds the delegations, the locking mechanism is inefficient. Thus every time when this routine is called, it will perform a series of down-up operation on a certain semaphore. This can result in a huge CPU cost when many threads calling the routine in parallel.

RESOLUTION:
The code is modified to optimize the locking mechanism in the routine to get the broadcast information of a node which contains maps of Allocation Units (AUs) for which node holds the delegations, so that it only does down-up operation on the semaphore once.

* 3617793 (Tracking ID: 3564076)

SYMPTOM:
The MongoDB noSQL db creation fails with an ENOTSUP error. MongoDB uses
posix_fallocate to create a file first. When it writes at offset which is not
aligned with File System block boundary, an ENOTSUP error comes up.

DESCRIPTION:
On a file system with 8k bsize and 4k page size, the application creates a file
using posix_fallocate, and then writes at some offset which is not aligned with
fs block boundary. In this case, the pre-allocated extent is split at the
unaligned offset into two parts for the write. However the alignment requirement
of the split fails the operation.

RESOLUTION:
Split the extent down to block boundary.

* 3620279 (Tracking ID: 3558087)

SYMPTOM:
Run simultaneous dd threads on a mount point and start the ls l command on the same mount point. Then the system hangs.

DESCRIPTION:
When the delayed allocation (dalloc) feature is turned on, the flushing process takes much time. The process keeps the glock held, and needs writers to keep the irwlock held. Thels l command starts stat internally and keeps waiting for irwlock to real ACLs.

RESOLUTION:
Redesign dalloc to keep the glock unlocked while flushing.

* 3620288 (Tracking ID: 3469644)

SYMPTOM:
The system panics in the vx_logbuf_clean() function when it  traverses chain of transactions off the intent log buffer. The stack trace is as follows:

vx_logbuf_clean ()
vx_logadd ()
vx_log()
vx_trancommit()
vx_exh_hashinit ()
vx_dexh_create ()
vx_dexh_init ()
vx_pd_rename ()
vx_rename1_pd()
vx_do_rename ()
vx_rename1 ()
vx_rename ()
vx_rename_skey ()

DESCRIPTION:
The system panics as the vx_logbug_clean() function tries to access an already freed transaction from transaction chain to flush it to log.

RESOLUTION:
The code has been modified to make sure that the transaction gets flushed to the log before it is freed.

* 3645825 (Tracking ID: 3622326)

SYMPTOM:
Filesystem is marked with fullfsck flag as an inode is marked bad
during checkpoint promote

DESCRIPTION:
VxFS incorrectly skipped pushing of data to clone inode due to
which the inode is marked bad during checkpoint promote which intern resulted in
filesystem being marked with fullfsck flag.

RESOLUTION:
Code is modified to push the proper data to clone inode.

Patch ID: 6.1.1.000

* 3383149 (Tracking ID: 3383147)

SYMPTOM:
The C operator precedence error may occur while turning off delayed
allocation.

DESCRIPTION:
Due to the C operator precedence issue, VxFS evaluates a condition
wrongly.

RESOLUTION:
The code is modified to evaluate the condition correctly.

* 3422580 (Tracking ID: 1949445)

SYMPTOM:
System is unresponsive when files are created on large directory. The following stack is logged:

vxg_grant_sleep()                                             
vxg_cmn_lock()
vxg_api_lock()                                             
vx_glm_lock()
vx_get_ownership()                                                  
vx_exh_coverblk()  
vx_exh_split()                                                 
vx_dexh_setup() 
vx_dexh_create()                                              
vx_dexh_init() 
vx_do_create()

DESCRIPTION:
For large directories, large directory hash (LDH) is enabled to improve the lookup feature. When a system takes ownership of LDH inode twice in same thread context (while building hash for directory), it becomes unresponsive

RESOLUTION:
The code is modified to avoid taking ownership again if we already have the ownership of the LDH inode.

* 3422584 (Tracking ID: 2059611)

SYMPTOM:
The system panics due to a NULL pointer dereference while flushing the
bitmaps to the disk and the following stack trace is displayed:
a|
a|
vx_unlockmap+0x10c
vx_tflush_map+0x51c
vx_fsq_flush+0x504
vx_fsflush_fsq+0x190
vx_workitem_process+0x1c
vx_worklist_process+0x2b0
vx_worklist_thread+0x78

DESCRIPTION:
The vx_unlockmap() function unlocks a map structure of the file
system. If the map is being used, the hold count is incremented. The
vx_unlockmap() function attempts to check whether this is an empty mlink doubly
linked list. The asynchronous vx_mapiodone routine can change the link at random
even though the hold count is zero.

RESOLUTION:
The code is modified to change the evaluation rule inside the
vx_unlockmap() function, so that further evaluation can be skipped over when map
hold count is zero.

* 3422586 (Tracking ID: 2439261)

SYMPTOM:
When the vx_fiostats_tunable is changed from zero to non-zero, the
system panics with the following stack trace:
vx_fiostats_do_update
vx_fiostats_update
vx_read1
vx_rdwr
vno_rw
rwuio
pread

DESCRIPTION:
When vx_fiostats_tunable is changed from zero to non-zero, all the
incore-inode fiostats attributes are set to NULL. When these attributes are
accessed, the system panics due to the NULL pointer dereference.

RESOLUTION:
The code has been modified to check the file I/O stat attributes are
present before dereferencing the pointers.

* 3422604 (Tracking ID: 3092114)

SYMPTOM:
The information output by the "df -i" command can often be inaccurate for 
cluster mounted file systems.

DESCRIPTION:
In Cluster File System 5.0 release a concept of delegating metadata to nodes in 
the cluster is introduced. This delegation of metadata allows CFS secondary 
nodes to update metadata without having to ask the CFS primary to do it. This 
provides greater node scalability. 
However, the "df -i" information is still collected by the CFS primary 
regardless of which node (primary or secondary) the "df -i" command is executed 
on.

For inodes the granularity of each delegation is an Inode Allocation Unit 
[IAU], thus IAUs can be delegated to nodes in the cluster.
When using a VxFS 1Kb file system block size each IAU will represent 8192 
inodes.
When using a VxFS 2Kb file system block size each IAU will represent 16384 
inodes.
When using a VxFS 4Kb file system block size each IAU will represent 32768 
inodes.
When using a VxFS 8Kb file system block size each IAU will represent 65536 
inodes.
Each IAU contains a bitmap that determines whether each inode it represents is 
either allocated or free, the IAU also contains a summary count of the number 
of inodes that are currently free in the IAU.
The ""df -i" information can be considered as a simple sum of all the IAU 
summary counts.
Using a 1Kb block size IAU-0 will represent inodes numbers      0 -  8191
Using a 1Kb block size IAU-1 will represent inodes numbers   8192 - 16383
Using a 1Kb block size IAU-2 will represent inodes numbers  16384 - 32768
etc.
The inaccurate "df -i" count occurs because the CFS primary has no visibility 
of the current IAU summary information for IAU that are delegated to Secondary 
nodes.
Therefore the number of allocated inodes within an IAU that is currently 
delegated to a CFS Secondary node is not known to the CFS Primary.  As a 
result, the "df -i" count information for the currently delegated IAUs is 
collected from the Primary's copy of the IAU summaries. Since the Primary's 
copy of the IAU is stale, therefore the "df -i" count is only accurate when no 
IAUs are currently delegated to CFS secondary nodes.
In other words - the IAUs currently delegated to CFS secondary nodes will cause 
the "df -i" count to be inaccurate.
Once an IAU is delegated to a node it can "timeout" after a 3 minutes  of 
inactivity. However, not all IAU delegations will timeout. One IAU will always 
remain delegated to each node for performance reasons. Also an IAU whose inodes 
are all allocated (so no free inodes remain in the IAU) it would not timeout 
either.
The issue can be best summarized as:
The more IAUs that remain delegated to CFS secondary nodes, the greater the 
inaccuracy of the "df -i" count.

RESOLUTION:
Allow the delegations for IAU's whose inodes are all allocated (so no free 
inodes in the IAU) to "timeout" after 3 minutes of inactivity.

* 3422614 (Tracking ID: 3297840)

SYMPTOM:
A metadata corruption is found during the file removal process with the inode block count getting negative.

DESCRIPTION:
When the user removes or truncates a file having the shared indirect blocks, there can be an instance where the block count can be updated to reflect the removal of the shared indirect blocks when the blocks are not removed from the file. The next iteration of the loop updates the block count again while removing these blocks. This will eventually lead to the block count being a negative value after all the blocks are removed from the file. The removal code expects the block count to be zero before updating the rest of the metadata.

RESOLUTION:
The code is modified to update the block count and other tracking metadata in the same transaction as the blocks are removed from the file.

* 3422626 (Tracking ID: 3332902)

SYMPTOM:
The system running the fsclustadm(1M) command panics while shutting down. The 
following stack trace is logged along with the panic:

machine_kexec
crash_kexec
oops_end
page_fault [exception RIP: vx_glm_unlock]
vx_cfs_frlpause_leave [vxfs]
vx_cfsaioctl [vxfs]
vxportalkioctl [vxportal]
vfs_ioctl
do_vfs_ioctl
sys_ioctl
system_call_fastpath

DESCRIPTION:
There exists a race-condition between "fsclustadm(1M) cfsdeinit"
and "fsclustadm(1M) frlpause_disable". The "fsclustadm(1M) cfsdeinit" fails
after cleaning the Group Lock Manager (GLM), without downgrading the CFS state.
Under the false CFS state, the "fsclustadm(1M) frlpause_disable" command enters
and accesses the GLM lock, which "fsclustadm(1M) cfsdeinit" frees resulting in a
panic.

Another race condition exists between the code in vx_cfs_deinit() and the code 
in
fsck, and it leads to the situation that although fsck has a reservation
held, but this couldn't prevent vx_cfs_deinit() from freeing vx_cvmres_list
because there is no such a check for vx_cfs_keepcount.

RESOLUTION:
The code is modified to add appropriate checks in the "fsclustadm(1M) 
cfsdeinit" and "fsclustadm(1M) frlpause_disable" to avoid the race-condition.

* 3422629 (Tracking ID: 3335272)

SYMPTOM:
The mkfs (make file system) command dumps core when the log size 
provided is not aligned. The following stack trace is displayed:

(gdb) bt
#0  find_space ()
#1  place_extents ()
#2  fill_fset ()
#3  main ()
(gdb)

DESCRIPTION:
While creating the VxFS file system using the mkfs command, if the 
log size provided is not aligned properly, you may end up in doing 
miscalculations for placing the RCQ extents and finding no place. This leads to 
illegal memory access of AU bitmap and results in core dump.

RESOLUTION:
The code is modified to place the RCQ extents in the same AU where 
log extents are allocated.

* 3422636 (Tracking ID: 3340286)

SYMPTOM:
The tunable setting of dalloc_enable gets reset to a default value
after a file system is resized.

DESCRIPTION:
The file system resize operation triggers the file system re-initialization
process. 
During this process, the tunable value of dalloc_enable gets reset to the
default value instead of retaining the old tunable value.

RESOLUTION:
The code is fixed such that the old tunable value of dalloc_enable is retained.

* 3422649 (Tracking ID: 3394803)

SYMPTOM:
The vxupgrade(1M) command causes VxFS to panic with the following stack trace:
panic_save_regs_switchstack()
panic
bad_kern_reference()
$cold_pfault()
vm_hndlr()
bubbleup()
vx_fs_upgrade()
vx_upgrade()
$cold_vx_aioctl_common()
vx_aioctl()
vx_ioctl()
vno_ioctl()
ioctl()
syscall()

DESCRIPTION:
The panic is caused due to de_referencing the operator in the NULL device (one
of the devices in the DEVLIST is showing as a NULL device).

RESOLUTION:
The code is modified to skip the NULL devices when the device in EVLIST is
processed.

* 3436431 (Tracking ID: 3434811)

SYMPTOM:
In VxFS 6.1, the vxfsconvert(1M) command hangs within the vxfsl3_getext()
Function with following stack trace:

search_type()
bmap_typ()
vxfsl3_typext()
vxfsl3_getext()
ext_convert()
fset_convert()
convert()

DESCRIPTION:
There is a type casting problem for extent size. It may cause a non-zero value to overflow and turn into zero by mistake. This further leads to infinite looping inside the function.

RESOLUTION:
The code is modified to remove the intermediate variable and avoid type casting.

* 3448503 (Tracking ID: 3448492)

SYMPTOM:
In Solaris SPARC, introduced Vnode Page Mapping (VPM) interface instead
of the legacy segmap interface.

DESCRIPTION:
For improved performance, the VPM interface is introduced, which
employs the kernel page mapping (KPM).

RESOLUTION:
The code is modified to support the VPM interface.

* 3501832 (Tracking ID: 3413926)

SYMPTOM:
Internal testing hangs due to high memory consumption resulting in fork failure

DESCRIPTION:
The issue of high swap usage  occurs with recent updates of Solaris10 and Solaris11. This issue is predominantly seen with internal stress/noise testing. The recent solaris update release had increased ncpu. As large number of buffer cache free lists in VxFS are spawned with respect to ncpu, there is high memory consumption which results in fork failure.

RESOLUTION:
For large number of CPU greater than 16, the number of buffer cache free lists is
adjusted according to the maximum number of CPU supported.

* 3504362 (Tracking ID: 3472551)

SYMPTOM:
The attribute validation (pass 1d) of full fsck takes too much time to complete.

DESCRIPTION:
The current implementation of full fsck Pass 1d (attribute inode validation) is single threaded. This causes slow full fsck performance on large file system, especially the ones having large number of attribute inodes.

RESOLUTION:
The Pass 1d is modified to work in parallel using multiple threads, which enables full fsck to process the attribute inode
validation faster.

SYMPTOM:
Internal test hits assert in voprwunlock.

DESCRIPTION:
In slow path write routine, the inode is not locked with Vnode Operation (VOP) read-write lock before returning to Operating System (OS).

RESOLUTION:
The code is modified to take VOP read-write lock in shared mode on inode before returning to OS.

* 3512292 (Tracking ID: 3348520)

SYMPTOM:
In a Cluster File System (CFS) cluster having multi volume file system of a smaller size, execution of the fsadm command causes system hang if the free space in the file system is low. The following stack trace is displayed:
 
vx_svar_sleep_unlock()
vx_extentalloc_device() 
vx_extentalloc()
vx_reorg_emap()
vx_extmap_reorg()
vx_reorg()
vx_aioctl_full()

DESCRIPTION:
While performing the fsadm operation, the secondary node in the CFS cluster is unable to allocate space from EAU (Extent Allocation Unit)
delegation given by the primary node. It requests the primary node for another delegation.
While giving such delegations, the primary node does not verify whether the EAU has exclusion zones set on it. It only verifies if it has enough free space.
On secondary node, the extent allocation cannot be done from EAU which has exclusion zone set, resulting in loop.

RESOLUTION:
The code is modified such that the primary node will not delegate EAU to the secondary node which have exclusion zone set on it.

* 3518943 (Tracking ID: 3534779)

SYMPTOM:
Internal stress testing on Cluster File System (CFS) hits a debug assert.

DESCRIPTION:
The assert was hit while refreshing the incore reference count
queue (rcq) values from the disk in response to a loadfs message. Due to which,
a race occurs with a rcq processing thread that has already advanced the incore
rcq indexes on a primary node in CFS.

RESOLUTION:
The code is modified to avoid selective updates in incore rcq.

* 3519809 (Tracking ID: 3463464)

SYMPTOM:
Internal kernel functionality conformance test hits a kernel panic due to null pointer dereference.

DESCRIPTION:
In the vx_fsadm_query()function, error handling code path incorrectly sets the nodeid to AnullA in the file system structure. As a result of clearing nodeid, any subsequent access to this field results in the kernel panic.

RESOLUTION:
The code is modified to improve the error handling code path.

* 3528770 (Tracking ID: 3449152)

SYMPTOM:
The vxtunefs(1M) command fails to set the thin_friendly_alloc tunable in CFS.

DESCRIPTION:
The thin_friendly_alloc tunable is not supported on CFS. But when the vxtunefs(1M) command is used to set it in CFS, a false successful message is displayed.

RESOLUTION:
The code is modified to report error for the attempt to set the thin_friendly_alloc tunable in CFS.

* 3529852 (Tracking ID: 3463717)

SYMPTOM:
CFS does not support the 'thin_friendly_alloc' tunable. And, the vxtunefs(1M) command  man page is not updated with this information.

DESCRIPTION:
Since the man page does not explicitly mention that the 'thin_friendly_alloc' tunable is not supported, it is assumed that CFS supports this feature.

RESOLUTION:
The man page pertinent to the vxtunefs(1M) command  is updated to denote that CFS does not support the  'thin_friendly_alloc' tunable.

* 3529862 (Tracking ID: 3529860)

SYMPTOM:
The package verification using the pkg verifyA command fails for
VRTSglm, VRTSgms, and VRTSvxfs packages on Solaris 11.

DESCRIPTION:
The package verification using the pkg verify command fails for
the Group Lock Manager (GLM), Group Messaging Services (GMS), and VxFS packages
on Solaris 11 due to a missing minor node permission '* 0640 root sys' from
etc/minor_perm file.

RESOLUTION:
The code is modified to update the entry in etc/minor_perm file.

* 3530038 (Tracking ID: 3417321)

SYMPTOM:
The vxtunefs(1M) man page gives an incorrect

DESCRIPTION:
According to the current design, the tunable Adelicache_enableA is
enabled by default both in case of local mount and cluster mount. But, the man
page is not updated accordingly. It still specifies that this tunable is enabled
by default only in case of a local mount. The man page needs to be updated to
correct the

RESOLUTION:
The code is modified to update the man page of the vxtunefs(1m) tunable to
display the correct contents for the Adelicache_enableA tunable. Additional
information is provided with respect to the performance benefits, in case of CFS
being limited as compared to the local mount.
Also, in case of CFS, unlike the other CFS tunable parameters, there is a need
to explicitly turn this tunable on or off on each node.

* 3541125 (Tracking ID: 3541083)

SYMPTOM:
The vxupgrade(1M) command for layout version 10 creates 64-bit quota
files with inappropriate permission configurations.

DESCRIPTION:
Layout version 10 supports 64-bit quota feature. Thus, while
upgrading to version 10, 32-bit external quota files are converted to 64-bit.
During this conversion process, 64-bit files are created without specifying any
permission. Hence, random permissions are assigned to the 64-bit file, which
creates an impression that the conversion process was not successful as expected.

RESOLUTION:
The code is modified such that appropriate permissions are provided
while creating 64-bit quota files.
